The majority were her 88-year-old mother's. In an emotional heart-to-heart scene, elderly Esther broke down in tears as she told for the first time of how tough she has found it to come to terms with her child's transition.

As she clutched her hands together, she said: "It's going to be so difficult for me to think of you as she, and say Caitlyn when I want to speak with you, or call your attention, 'Hey Caitlyn' instead of, 'Hey Bruce.'

“You look so much like someone in my family and I was trying to figure it out, it's not easy, it's not easy.

“But your values are always going to be the same, Bruce will still be there, yo have the same soul, you have the same soul as you were born with.

“I love Bruce, it will never change. Its going to take some getting used to, I want to do what he wants.

“The problem before with you and I, I'm guessing this, is that you felt uncomfortable with me, we would see each other and it was like you wanted to get away.”

Caitlyn replied: “I was an isolationist, I isolated myself from the world because I didn't fit in, I was kind of stuck in the middle. Caitlyn fits into society better than Bruce.

“I'm very optimistic about the future and I'm dragging you along with me.”

Caitlyn visited the family of a young boy named Kyler Prescott who killed himself for not being able to deal with being transgender, and she spoke of how her mission is to cut suicides in the community.
